Description

Technical Field

[0001] This utility model relates to the field of electrical switch technology, and in particular to a switch that is easy to install quickly. Background Technology

[0002] A switch is a commonly used power distribution product for controlling the on / off state of electrical circuits, widely used in power, railway, communications, construction, agriculture, and industry. Currently, commonly used switches have wire mounting holes at both ends, secured with screws, and are internally electrically connected. The circuit is controlled by a front-end operating mechanism, and the most common configuration is top-in, bottom-out. When multiple switches are used in parallel, a busbar needs to be installed on one side of the switch to supply power to multiple terminals simultaneously. Each switch's mounting screws must be tightened, resulting in low installation efficiency. If a switch malfunctions and needs replacement, the entire busbar must be removed, and the busbar reinstalled after replacing the switch. This process is prone to errors, such as forgetting to tighten certain switch mounting screws, and the disassembly and reassembly of the busbar is time-consuming and labor-intensive, increasing maintenance time and labor costs.

[0003] Therefore, it is necessary to design a switch that can be quickly installed and replaced and is easy to operate. Utility Model Content

[0028] Example

[0029] A switch that is easy to install quickly, such as Figure 1 and Figure 2 As shown, the device includes a housing 1, an operating mechanism 2, a positive electrode wire mounting hole 7, and a negative electrode wire mounting hole 8. A first conductive element 9 and a second conductive element 10 are respectively located at the bottom of the positive electrode wire mounting hole 7 and the negative electrode wire mounting hole 8. A positive electrode copper busbar slot 3 and a negative electrode copper busbar slot 4 are located on the side wall of the housing 1 away from the operating mechanism 2. A third conductive element 12 and a fourth conductive element 13 located inside the housing 1 are respectively located on one side of the positive electrode copper busbar slot 3 and the negative electrode copper busbar slot 4. The connection and disconnection of the first conductive element 9 and the third conductive element 12, and the second conductive element 10 and the fourth conductive element 13 are controlled by the operating mechanism 2. The operating mechanism 2 adopts a conventional operating mechanism in the prior art. Figure 2 and Figure 4 The specific structure of the operating mechanism 2 is omitted.

[0030] Both the positive electrode mounting hole 7 and the negative electrode mounting hole 8 are located on the top of the housing 1 and are adjacent to each other along the width direction of the housing 1. The positive electrode mounting hole 7 is positioned higher than the negative electrode mounting hole 8. The axes of both the positive electrode mounting hole 7 and the negative electrode mounting hole 8 are perpendicular to the horizontal plane, and the planes of their openings are parallel to the horizontal plane. A first conductive element 9 and a second conductive element 10 are respectively provided at the bottom of the positive electrode mounting hole 7 and the negative electrode mounting hole 8. Fastening screws 11 are provided on the side walls of both the positive electrode mounting hole 7 and the negative electrode mounting hole 8. During installation, the positive electrode output wire and the negative electrode output wire are inserted into the positive electrode mounting hole 7 and the negative electrode mounting hole 8 respectively, ensuring full contact and connection between the positive electrode output wire and the first conductive element 9 and the second conductive element 10, and then the fastening screws 11 are tightened for fixation.

[0031] A PCB slot 5 is also provided between the positive copper busbar slot 3 and the negative copper busbar slot 4; a fifth conductive element 14 is provided inside the housing 1 on one side of the PCB slot 5.

[0032] like Figure 3 As shown, the positive copper busbar slot 3, the negative copper busbar slot 4, and the PCB slot 5 are each provided with a spring clip 6 on their two opposite side walls. In use, the positive copper busbar, negative copper busbar, and PCB are inserted into the positive copper busbar slot 3, negative copper busbar slot 4, and PCB slot 5, respectively. The spring clips 6 connect the positive and negative copper busbars to the third conductive element 12 and the fourth conductive element 13, respectively, and the PCB to the fifth conductive element 14. The spring clips 6 also clamp and secure the positive copper busbar, negative copper busbar, and PCB.

[0033] By manipulating the operating mechanism 2, the first conductive element 9 is connected to the third conductive element 12, and the second conductive element 10 is connected to the fourth conductive element 13, forming a circuit with the positive output wire, the negative output wire, the positive copper busbar, and the negative copper busbar. When the fifth conductive element 14 is connected to the PCB via the spring contact 6, the address bit of this switch is selected by the PCB.

[0034] The positive copper busbar slot 3, the negative copper busbar slot 4, and the PCB slot 5 all have open ends, and all three are U-shaped and parallel to each other. In use, the positive copper busbar, negative copper busbar, and PCB are simply inserted into their respective slots, making operation simple and convenient.

[0035] A latch 15 is provided on the upper part of the rear side wall of housing 1 (i.e., the side wall away from operating mechanism 2), and the latch 15 engages with the switch rail inside the electrical control box. The latch 15 adopts a conventional latch structure in the prior art, therefore... Figure 1 , Figure 2 and Figure 4 The specific structure of buckle 15 is omitted.

[0036] The housing 1 can be made of plastic material commonly used for switches in this field.

[0037] The method of using the switch provided in this embodiment is as follows: When the switch is connected, such as Figure 4As shown, the positive copper busbar slot 3, negative copper busbar slot 4, and PCB slot 5 on the rear side of the housing 1 are directly snapped onto the positive copper busbar 16, negative copper busbar 17, and PCB 18 inside the electrical control box. The input wire only needs to be connected to one end of the copper busbar. The switch is fixed to the guide rail 19 inside the electrical control box by the clip 15. After snapping, the positive copper busbar 16 and negative copper busbar 17 are connected to the third conductive element 12 and the fourth conductive element 13 respectively via the spring contact 6. The PCB 18 is connected to the fifth conductive element 14 via the spring contact 6. The positive and negative output wires are installed in the positive wire mounting hole 7 and the negative wire mounting hole 8 respectively using fastening screws 11. The operating mechanism 2 connects the first conductive element 9 to the third conductive element 12 and the second conductive element 10 to the fourth conductive element 13. If multiple sets of output wires are required, multiple switches can be snapped onto the same copper busbar sequentially. Figure 5 As shown.

[0038] When the switch needs to be replaced, turn the fastening screw 11 to remove the positive output wire and the negative output wire, pry up the clip 15, and pull the switch out directly. Replacing any one of the multiple sets of switches will not affect each other.

[0039] Switches commonly used in the prior art, such as Figure 6 and Figure 7 As shown, its two wire mounting holes are located at the top and bottom of the housing, respectively. During electrical installation, wires need to be installed from the top and bottom of the switch, respectively. In the limited space of the distribution box or electrical cabinet, the routing and arrangement of wires are restricted, increasing the difficulty and workload of wiring, and also making it inconvenient for later inspection and maintenance. This invention, however, places the two wire mounting holes at the top of the switch, allowing all wires to be connected from the top of the switch. This makes the wiring more centralized and orderly, making it easier to plan the routing of wires in the distribution box or electrical cabinet, facilitating organization and bundling, and making the entire wiring system neater and more aesthetically pleasing. It also facilitates later inspection and maintenance, and better utilizes the space below the switch, making the layout of electrical equipment or the installation environment more compact and reasonable.

[0040] Traditional switches are often connected to copper busbars using bolts, which is cumbersome and requires tools. This invention, however, uses a switch with corresponding slots and springs, allowing for tool-free connection to the copper busbar and PCB; simply insert the switch. This simplified operation solution is straightforward.

[0041] The switch provided by this utility model is easy to assemble and disassemble quickly, has strong versatility, and is simple to operate. It can improve work efficiency, avoid live work, and improve personal safety.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
